SYSTEM FOR CORRECTING WELDING LINE OF AN AUTOMATIC WELDING MACHINE.

摘要

A system for correcting welding lines of an automatic welding machine comprises detecting means (I) for detecting a welding current that flows between the tip of a wire (WR) and a welding member (WK), memory means for storing the welding current detected by the detecting means (I) at either the right end point or the left end point of the welding line during the weaving movement, and operation means for operating the correction amount of the weaving movement based upon the current values at two or more end points stored in said memory means.
